  • 18. Availability Features OmniSwitch 6850/6850E SeriesAvailability Features The switch provides a broad variety of availability features. Availability features are hardware and software-based safeguards that help to prevent the loss of data flow in the unlikely event of a subsystem failure. In addition, some availability features allow users to maintain or replace hardware components without powering off the switch or interrupting switch operations. Combined, these features provide added resiliency and help to ensure that the switch or virtual chassis is consistently available for day-to-day network operations. Hardware-related availability features include: • Software Rollback • Backup Power Supplies • Hot Swapping • Hardware MonitoringSoftware Rollback Software rollback (also referred to as image rollback) essentially allows the OmniSwitch to return to a prior “last known good” version of software in the event of a system software problem. The switch controls software rollback through its resilient directory structure design (i.e., /flash/working and /flash/ certified). For detailed information on the software rollback feature, as well as the switch’s /flash/working and /flash/certified directories, refer to the “Managing CMM Directory Content” chapter in the OmniSwitch AOS Release 6 Series Switch Management Guide.Backup Power Supplies The switches support an optional backup power supply. This power supply is connected to the rear of the unit and provides redundant chassis power on a 1:1 basis. There is a power shelf provided with the unit that slides into the rear of the chassis and is used to hold the power supplies. Backup power supplies operate in active standby mode. If the primary power supply fails unexpectedly, the backup power supply automatically takes up the full power load without disrupting the switch.page 1-2 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 19. OmniSwitch 6850/6850E Series Availability FeaturesHot Swapping Hot swapping refers to the action of adding, removing, or replacing components without powering off switches or disrupting other components.This feature facilitates hardware upgrades and maintenance and allows users to easily replace components in the unlikely event of hardware failure. The following hardware components can be hot swapped: • Backup power supply • Backup power supply connector cables • SFPs For instructions on hot swapping backup power supplies, refer to Chapter 2, “OmniSwitch 6850 Series Chassis and Hardware Components.”.Hardware Monitoring Automatic Monitoring Automatic monitoring refers to the switch’s built-in sensors that automatically monitor operations. If an error is detected (e.g., over-threshold temperature), the switch immediately sends a trap to the user. The trap is displayed on the console in the form of a text error message. (In the case of an over-threshold temperature condition, the chassis displays an amber TMP LED in addition to sending a trap.) LEDs LEDs, which provide visual status information, are provided on the chassis front panel. LEDs are used to indicate conditions such as hardware and software status, temperature errors, link integrity, data flow, etc. For detailed LED descriptions, refer to Chapter 2, “OmniSwitch 6850 Series Chassis and Hardware Components.” User-Driven Monitoring User-driven hardware monitoring refers to CLI commands that are entered by the user in order to access the current status of hardware components. The user enters “show” commands that output information to the console. Monitoring information for chassis components, such as the optional back up power supply, chassis temperature sensor, and chassis fans is provided in Chapter 2, “OmniSwitch 6850 Series Chassis and Hardware Components.” The show commands for all the features are described in detail in the OmniSwitch CLI Reference Guide.OmniSwitch 6850/6850E Series Hardware Users Guide June 2011 page 1-3

  • 78. Mounting the Switch OmniSwitch 6850 Series Chassis and Hardware ComponentsBlank Cover Panels Blank cover panels are provided with your switch and are used to cover empty backup power supply bays and 10 Gigabit uplink bays (all OmniSwitch 6850 Series switches, except for OmniSwitch 6850-24, OmniSwitch 6850-P24, OmniSwitch 6850-48, and OmniSwitch 6850-P48). These cover panels play an important role in chassis airflow and temperature management. They also protect the switch’s processor board and other sensitive internal switch components from physical damage by closing off the chassis. When blank cover panels are missing, air does not take the direct route from the air intake vent, through the chassis, and then out through the fan exhaust vents (see page 2-57). Instead, a portion of the airflow is allowed to be drawn in through the rear of the chassis. As a result, normal airflow is disrupted and an extra task is placed on the fans to cool the chassis. If your switch is not equipped with a backup power supply connection or 10 Gigabit uplink, and blank cover panels are not installed over empty bay locations, airflow is adversely affected. Since they regulate airflow and help protect internal chassis components, blank cover panels should remain installed over empty bays at all times.page 2-58 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 79. OmniSwitch 6850 Series Chassis and Hardware Components Mounting the SwitchInstallation Options The OmniSwitch 6850 Series switches can be installed in two ways: • Tabletop installation • Rack-mount installationInstalling the Switch on a Tabletop or Bench OmniSwitch 6850 Series switches can be installed freestanding as tabletop units. Place your switch on a stable, flat, and static-free surface. Note. OmniSwitch 6850 Series switches must be placed “right side up.” Never attempt to operate a switch positioned on its side. Tabletop Mounting Steps To install the switch as a tabletop unit, follow the steps below: 1 Position the chassis on the table or bench where it is to be installed. 2 Be sure that adequate clearance has been provided for chassis airflow and access to the front, back, and sides of the switch. For recommended clearances, refer to page 2-56. Also, be sure that you have placed the chassis within the reach of all the required AC power sources. 3 If you are installing a single (i.e., stand-alone) switch, continue to “Setting Up a Stacked Configura- tion” on page 2-62 for additional setup procedures. If you are placing multiple switches in a stacked configuration, carefully stack the remaining switches, one on top of the other. Up to eight switches may be stacked to form a single virtual chassis. Be sure to main- tain adequate clearance at the front, rear, left, and right side of all switches (see page 2-56). Also, be sure that you have placed all switches in the stack within reach of required AC power sources. Once the switches are stacked together, continue to “Cabling Stacked Configurations” on page 2-62 for additional setup procedures. Note. Switches should be added one at a time in a stack. Note. For comprehensive information on operating switches in a stacked configuration, refer to Chapter 6, “Managing OmniSwitch 6850/6850E Series Stacks.”OmniSwitch 6850/6850E Series Hardware Users Guide June 2011 page 2-59
  • 80. Mounting the Switch OmniSwitch 6850 Series Chassis and Hardware ComponentsRack-Mounting the Switch Refer to the important guidelines below before installing the OmniSwitch 6850 Series chassis on a rack. • It is recommended that two people install the switch on the rack—one person to hold the chassis and position it on the rack, and a second person to secure the chassis to the rack using attachment screws (not supplied). • Alcatel-Lucent provides two rack-mount flanges with each OmniSwitch 6850 Series switch. These flanges support standard 19-inch rack-mount installations. These flanges must be attached to the chas- sis before the switch can be rack mounted. Note. If you are installing the switch in a 23-inch-wide rack, Alcatel-Lucent offers optional 23-inch rack- mounting hardware. For more information, contact your Alcatel-Lucent representative. • Alcatel-Lucent does not provide rack-mount screws. Use the screws supplied by the rack vendor. • To prevent a rack from becoming top heavy, it is recommended that you install heavier equipment at the bottom of the rack, whenever possible. • If you are installing the switch on a relay rack, be sure to install and secure the rack per the rack manu- facturer’s specifications. • Review page 2-56 for important chassis airflow and access recommendations before installing. Rack Mounting Steps To rack-mount the switch, follow the steps below: 1 Align the holes in the provided rack-mount flanges with the four threaded holes in the OmniSwitch 6850 Series chassis. These threaded holes are located in the left and right sides of the chassis, near the front panel. 2 Attach the flanges to the chassis using the provided Phillips-head screws. Be sure to tighten each of the screws firmly using a Phillips screwdriver. 45 46 le nso Co Attaching a Rack-Mount Flangepage 2-60 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 81. OmniSwitch 6850 Series Chassis and Hardware Components Mounting the Switch 3 After the rack-mount flanges are secured to the chassis, mark the holes on the rack where the switch is to be installed. 4 Lift and position the switch until the rack-mount flanges are flush with the rack post. 5 Align the holes in the flanges with the rack holes that were marked in step 3. 6 Once the holes are aligned, insert a rack mount screw (not provided) through the bottom hole of each flange. Tighten both screws until they are secure. Attaching the Switch to the Rack Note. Be sure to install the screws in the bottom hole of each flange, as shown, before proceeding. 7 Once the screws at the bottom of each flange are secure, install the remaining two rack mount screws. Be sure that all screws are securely tightened. Note. If you are installing multiple switches in a rack to form a stacked configuration, refer to “Setting Up a Stacked Configuration” on page 2-62.Installing and Removing Combo Port SFPs OmniSwitch 6850 Series switches offer four Gigabit Ethernet combo ports, located on the front panel (see page 2-22). These combo ports support hot-swappable fiber Small Form-Factor Pluggables (SFPs). For instructions on installing and removing combo connector SFPs, refer to the OmniSwitch Transceivers Guide.OmniSwitch 6850/6850E Series Hardware Users Guide June 2011 page 2-61
  • 82. Setting Up a Stacked Configuration OmniSwitch 6850 Series Chassis and Hardware ComponentsSetting Up a Stacked ConfigurationRack Mounting Stacked Configurations To rack mount a stacked configuration, install all switches that are to be included in the stacked configura- tion as described on pages 2-60 through 2-61. Up to eight switches may be stacked to form a single virtual chassis. Note. You cannot mix OS6800 and OS6850 switches in a stack. Note. When rack mounting multiple switches in a stacked configuration, be sure to place all switches in vertically-adjacent rack positions. This will ensure that all required stacking cables will have adequate length for the installation.Cabling Stacked Configurations In order to connect stacked switches into a virtual chassis, all modules in the stack must be connected via stacking cables (provided).Redundant Stacking Cable Connections In addition to the stacking cables installed between adjacent switch, the top-most switch and bottom-most switch in the stack must be connected using a redundant stacking cable. Refer to Chapter 6, “Managing OmniSwitch 6850/6850E Series Stacks” for more information on the redundant stacking cable connection.Supported Cabling Patterns Each switch provides two stacking: stacking port A and stacking port B. Cables can be connected in any pattern. In other words, the cable connected to stacking port A of one switch can be connected to either stacking port A or stacking port B of the adjacent switch. However, it is strongly recommended that the cabling pattern remains consistent across the stack. For a cabling diagram and additional information on cabling the stack, refer to Chapter 6, “Managing OmniSwitch 6850/6850E Series Stacks.” Cabling Steps 1 Before inserting a stacking cable into one of the stacking, be sure to orient the stacking cable connec- tor properly. The wide portion of the connector must be facing up. Refer to the diagram below for more information. Connector Top When orienting the stacking cable connector, be sure that the wider portion of the connector is facing up as shown. Otherwise, the stacking cable will not fit properly in the chassis’ stacking port. End View of Stacking Cable Connectorpage 2-62 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 83. OmniSwitch 6850 Series Chassis and Hardware Components Setting Up a Stacked Configuration 2 Starting from the top of the stack, insert one end of the stacking cable into either stacking port A or stacking port B. The stacking port (A or B) depends on your preferred cabling pattern. Refer to Chapter 6, “Managing OmniSwitch 6850/6850E Series Stacks” for detailed information on cabling patterns. Be sure that cable connector is completely inserted and fully seated in the chassis. 3 Insert the other end of the stacking cable into the stacking port of the switch immediately below. Once again, the stacking port (A or B) depends on the preferred cabling pattern. 4 Repeat this procedure until all switches in the stack are connected (see illustrations a, b, and c below). Reminder. The diagram below shows one supported stacking cable pattern.

  • 88. Console Port OmniSwitch 6850 Series Chassis and Hardware ComponentsConsole Port The console port, located on the chassis front panel, provides a console connection to the switch and is required when logging into the switch for the first time. By default, this RJ-45 connector provides a DTE console connection.Serial Connection Default Settings The factory default settings for the serial connection are as follows: baud rate 9600 parity none data bits (word size) 8 stop bits 1 flow control noneModifying the Serial Connection SettingsThe switch’s serial connection defaults are listed above. If you wish to modify the default serial connectionsettings (i.e., baud rate, parity, data bits, and stop bits), refer to the following steps: Note. You must be connected to the switch via the console port before attempting to change serial connec- tion settings. Otherwise, an error message will display. For switches in a stacked configuration, all changes must be configured before the switches are cabled together. In other words, you must configure these settings when each switch is operating as a stand-alone unit. 1 Enter the modify boot parameters command at the CLI prompt. The boot prompt displays: Boot > 2 To change the baud rate, enter boot serialbaudrate, followed by the desired baud rate value. Options include 1200, 2400, 4800, 9600 (default), 19200, 38400, 57600, 76800, and 115200. For example: Boot > boot serialbaudrate 19200 Note. Setting the console port to speeds above 9600 baud can cause problems with Zmodem uploads. 3 To change the parity value, enter boot serialparity, followed by the desired parity value. Options include none (default), even, and odd.

  • 124. Console Port OmniSwitch 6850E Series Chassis and Hardware ComponentsConsole Port The console port, located on the chassis front panel, provides a console connection to the switch and is required when logging into the switch for the first time. By default, this RJ-45 connector provides an RS- 232 DTE console connection.Serial Connection Default Settings The factory default settings for the serial connection are as follows: baud rate 9600 parity none data bits (word size) 8 stop bits 1 flow control noneModifying the Serial Connection Settings The switch’s serial connection defaults are listed above. If you wish to modify the default serial connec- tion settings (i.e., baud rate, parity, data bits, and stop bits), refer to the following steps: Note. You must be connected to the switch via the console port before attempting to change serial connec- tion settings. Otherwise, an error message will display. For switches in a stacked configuration, all changes must be configured before the switches are cabled together. In other words, you must configure these settings when each switch is operating as a stand-alone unit. 1 Enter the modify boot parameters command at the CLI prompt. The boot prompt displays: Boot > 2 To change the baud rate, enter boot serialbaudrate, followed by the desired baud rate value. Options include 1200, 2400, 4800, 9600 (default), 19200, 38400, 57600, 76800, and 115200. For example: Boot > boot serialbaudrate 19200 Note. Setting the console port to speeds above 9600 baud can cause problems with Zmodem uploads. 3 To change the parity value, enter boot serialparity, followed by the desired parity value. Options include none (default), even, and odd. For example: Boot > boot serialparity even 4 To change the data bits (i.e., word size) value, enter boot serialwordsize, followed by the number of data bits. Options include 7 and 8 (default). For example: Boot > boot serialwordsize 7page 3-32 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 125. OmniSwitch 6850E Series Chassis and Hardware Components Console Port 5 To change the stop bits value, enter boot serialstopbits, followed by the number of stop bits. Options include 1 (default) and 2. For example: Boot > boot serialstopbits 2 6 Verify your current changes by entering show at the boot prompt: Boot > show Edit buffer contents: Serial (console) baud : 19200 Serial (console) parity : even Serial (console) stopbits : 2 Serial (console) wordsize : 7 (additional table output not shown) 7 You can save your changes to the boot.params file by entering commit file at the boot prompt: Boot > commit file When the commit file command is used, changes will not be enabled until after the next switch reboot. 8 You can also save your changes in real time to the switch’s running memory by entering commit system at the boot prompt: Boot > commit system Note. There are two important things to consider when using the commit system command to save serial connection changes: • Output to the terminal may become illegible due to incompatible serial connection settings between the switch and the terminal emulation software. • If you use the commit system command only, changes will not be saved to the switch’s boot.params file and will be lost if the switch is rebooted. To save changes to the boot.params file, refer to step 7. 9 Return to the CLI prompt by entering exit at the boot prompt.OmniSwitch 6850/6850E Series Hardware Users Guide June 2011 page 3-33

A small flat-tip screwdriver and a wire stripper are required for this procedure. 1 Prepare the three (3) wires—12 gauge—that will plug into the power supply. First make sure they are not plugged into the DC power source. Next, use a wire stripper to carefully strip between .24 and .30 inches (6-7.5 mm) off the end of each wire, removing the outer insulation to expose the copper core. 2 Open the clamp for the ground wire slot by inserting a small flat-tip screwdriver into the top of the appropriate circular hole. Loosen the screw so that the clamp for the ground wire opens. Loosen Screw. + - Clamp inside square hole will open when screw is loosened in top cir- cular hole. Opening Connector for Ground Wire 3 Insert the ground wire lead into the slot. The lead you insert must match the lead attached to the DC power source. Warning. You must plug DC wire leads into the correct holes in the DC power connector. Use the labels above the DC power connector as a guide to positive, negative, and ground connections. If the wire leads are plugged into the wrong holes, the power supply will not work properly and damage to the unit may result.

  • 151. 5 Managing Power over Ethernet (PoE) Power over Ethernet (PoE) provides inline power directly from the switch’s Ethernet. Powered Devices (PDs) such as IP phones, wireless LAN stations, Ethernet hubs, and other access points can be plugged directly into the Ethernet. From these RJ-45 the devices receive both electrical power and data flow. As the feature reduces devices’ dependence on conventional power sources, PoE eliminates many restric- tions that traditional electrical considerations have imposed on networks. In a PoE configuration, Power Source Equipment (PSE) detects the presence of a PD and provides an elec- trical current that is conducted along the data cable. The PD operates using the power received via the Ethernet data cable; no connection to an additional power source (e.g., an AC wall socket) is required. Note on Terminology. There are several general terms used to describe the feature, PoE. The terms Power over Ethernet (PoE), Power over LAN (PoL), Power on LAN (PoL), and Inline Power are synonymous terms used to describe the powering of attached devices via Ethernet. For consistency, this chapter and the CLI Command Reference Guide refer to the feature as Power over Ethernet (PoE). Additional terms, such as Powered Device (PD) and Power Source Equipment (PSE) are not synonymous with PoE, but are directly related to the feature: • PD refers to any attached device that uses a PoE data cable as its only source of power. Examples include access points, such as IP telephones, Ethernet hubs, wireless LAN stations, etc. • PSE refers to power sourcing equipment, which provides power to a single link section. PSE main functions include searching the PD, optionally classifying the PD, supplying power to the link section only if the PD is detected, monitoring the power on the link section, and scaling power back to detect level when power is no longer requested or required. As the switches fully support 10/100/1000 Ethernet connectivity, you may also attach non-PD equipment, such as computer workstations, printers, servers, etc. to the PoE ports. Important. Alcatel-Lucent recommends that PoE-enabled switches with attached IP telephones should have operational power supply redundancy at all times for 911 emergency requirements. In addition, both the switch and the power supply should be plugged into an Uninterruptible Power Source (UPS).OmniSwitch 6850/6850E Series Hardware Users Guide June 2011 page 5-1

If unlike power supplies are mixed or if an unsupported power supply (such as a 120W power supply) is used, a console message and a trap are generated.PoE Class Detection Powered devices can be classified into different classes as shown in the table below. Class detection allows for automatic maximum power adjustment based on the power class detected. This will prevent the switch from delivering more than the maximum power allowed based on a device’s class. During class detection the switch will allocate the maximum amount of power allowed based on the class detected. Once powered, if the device uses less than the maximum the remaining power will be made available for other devices.

  • 156. Configuring Power over Ethernet Parameters Managing Power over Ethernet (PoE)Setting the PoE Operational Status Enabling PoE By default, Power over Ethernet is administratively enabled in the switch’s system software. However, in order to physically activate PoE, you must issue the lanpower start command on a slot-by-slot basis before any connected PDs will receive inline power. To activate power to PoE-capable in a switch, enter the corresponding slot number only. For example: -> lanpower start 3 If power to a particular port has been disconnected via the lanpower stop command, you can reactivate power to the port by specifying both the slot and port in the command line. For example: -> lanpower start 3/11 Note. You cannot use the slot/port syntax to initially activate PoE on a port. This syntax is intended only to reactivate power to those that have been disconnected via the lanpower stop command. To initially activate PoE, you must use the lanpower start slot syntax only, as described above. Disabling PoE To disable PoE on a particular slot or port, use the lanpower stop command. To disable PoE on a specific PoE-capable port, enter a slot/port number. For example: -> lanpower stop 8/22 To disable PoE for all PoE-capable in a slot, enter the corresponding slot number only. For example: -> lanpower stop 8Configuring the Total Power Available to a Port By default, each port is authorized by the system software to use up to a maximum amount of milliwatts to power any attached device. You can either increase or decrease this value based on the allowed ranges specified in Chapter 5, “Managing Power over Ethernet (PoE).” Increasing the total power available to an individual port may provide a more demanding Powered Device (PD) with additional power required for operation. Decreasing the total power available to a port helps to preserve inline power and assists in the overall management of the switch’s power budget. To increase or decrease the total power available to an individual port, use the lanpower power command. Since you are setting the power allowance for an individual port, you must specify a slot/port number in the command line. For example, the syntax -> lanpower 3/12 power 3000 reduces the power allowance on slot 3 port 12 to 3000 milliwatts. This new value is now the maximum amount of power the port can use to power any attached device (until the value is modified by the user).page 5-6 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 157. Managing Power over Ethernet (PoE) Configuring Power over Ethernet ParametersConfiguring the Total Power Available to a slot Like the maximum port power allowance, the system software also provides a maximum slot-wide power allowance. By default, each slot is authorized by the system software to use a number of watts to power all devices connected to its ports depending on which power supply is used. As with the maximum port power allowance, the user can either increase or decrease this value based on the allowed ranges specified in Chapter 5, “Managing Power over Ethernet (PoE).” Note: Increasing or decreasing the total power available to a slot is designed for use on chassis-based products which share PoE power among the slots. For stackable products this command has no affect on other stack elements since each switch has a dedicated power supply. Important. Decreasing the slot-wide power could cause lower priority ports to lose power if the new value is less than the total PoE power currently being consumed. To increase or decrease the total power available to a slot, use the lanpower maxpower command. Since you are setting the power allowance for an individual slot, you must specify a slot number in the command line. For example, the syntax -> lanpower 3 maxpower 80 reduces the power allowance of slot 3 to 80 watts. This value is now the maximum amount of power the slot can use to power all attached devices (until the value is modified by the user). Note. Changing the maximum power available to a slot or port does not reserve or immediately allocate that power. These settings are only used for configuring a maximum amount of power that may be used, any unused power is still available and remains a part of the overall PoE budget.Setting Port Priority Levels As not all Powered Devices (PDs) connected to the switch have the same priority within a network setting, the OmniSwitch allows the administrator to specify priority levels on a port-by-port basis. Priority levels include low, high, and critical. The default priority level for a port is low. • Low. This default value is used for port(s) that have low-priority devices attached. In the event of a power management issue, inline power to low-priority is interrupted first (i.e., before critical and high- priority). • High. This value is used for port(s) that have important, but not mission-critical, devices attached. If other ports in the chassis have been configured as critical, inline power to high-priority is given second priority. • Critical. This value is used for port(s) that have mission-critical devices attached, and therefore require top (i.e., critical) priority. In the event of a power management issue, inline power to critical is main- tained as long as possible. To change the priority level for a particular port, use the lanpower priority command. Since the switch allows you to set priority levels on a port-by-port basis, be sure to specify slot/port information in the command line. For example, the syntax -> lanpower 8/22 priority criticalOmniSwitch 6850/6850E Series Hardware Users Guide June 2011 page 5-7
  • 158. Configuring Power over Ethernet Parameters Managing Power over Ethernet (PoE) changes the priority value of port 22 of the OmniSwitch 6850 Series slot 8 to the highest priority level of critical. Now that the default value has been reconfigured, this port should be reserved for those PDs that are mission critical for network operations.Setting the Capacitor Detection Method By default, the PowerDsine capacitor detection method is disabled. To enable it, use the lanpower capaci- tor-detection command by entering lanpower capacitor-detection followed by the slot number of the switch and enable. For example, to enable the capacitor detection method on the switch with slot number 2, enter: -> lanpower capacitor-detection 2 enable To disable it, use the lanpower capacitor-detection command by entering lanpower capacitor-detec- tion followed by the slot number and disable. For example, to disable the capacitor detection method on slot number 2, enter: -> lanpower capacitor-detection 2 disable Note. The capacitive detection method should only be enabled to support legacy IP phones. This feature is not compatible with IEEE specifications. Please contact your Alcatel-Lucent sales engineer or Customer Support representative to find out which Alcatel-Lucent IP phones models need capacitive detection enabled.page 5-8 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 159. Managing Power over Ethernet (PoE) Understanding Priority DisconnectUnderstanding Priority Disconnect The priority disconnect function differs from the port priority function described on page 5-7 in that it applies only to the addition of powered devices (PDs) in tight power budget conditions. Priority discon- nect is used by the system software in determining whether an incoming PD will be granted or denied power when there are too few watts remaining in the PoE power budget for an additional device. For example, if there are only 2 watts available in the current PoE power budget and a user plugs a 3.5W powered device into a PoE port, the system software must determine whether the device will be powered on. Based on priority disconnect rules, in some cases one or more existing devices may be powered down in order to accommodate the incoming device. In other cases, the incoming device will be denied power. Priority disconnect rules involve the port priority status of an incoming device (i.e., low, high, and criti- cal), as well as the port’s physical port number (i.e., 1–24). Understanding priority disconnect rules is especially helpful in avoiding power budget deficits and the unintentional shutdown of mission-critical devices when PDs are being added in tight power budget conditions. For detailed information on how priority disconnect uses port priority and port number criteria for determining the power status of incom- ing PDs, refer to the illustrated examples on pages 5-10 through 5-11. Reminder. Priority disconnect applies only when there is inadequate power remaining in the power budget for an incoming device. For information on setting the priority disconnect status, refer to the section below. For information on setting the port priority status (a separate function from priority disconnect), refer to “Setting Port Priority Levels” on page 5-7.Setting Priority Disconnect Status By default, priority disconnect is enabled in the switch’s system software. For information on changing the priority disconnect status, refer to the information below.Disabling Priority Disconnect When priority disconnect is disabled and there is inadequate power in the budget for an additional device, power will be denied to any incoming PD, regardless of its port priority status (i.e., low, high, and criti- cal) or physical port number (i.e., 1–24). To disable priority disconnect, use the lanpower priority-disconnect command. Since the switch allows you to set priority disconnect status on a slot-by-slot basis, be sure to specify the slot number in the command line. For example, the syntax -> lanpower 2 priority-disconnect disable disables the priority disconnect function on slot 2.Enabling Priority Disconnect To enable priority disconnect, use the lanpower priority-disconnect command. Be sure to specify the slot number in the command line. For example, the syntax -> lanpower 8 priority-disconnect enable enables priority disconnect on slot 8.OmniSwitch 6850/6850E Series Hardware Users Guide June 2011 page 5-9
  • 160. Understanding Priority Disconnect Managing Power over Ethernet (PoE)Priority Disconnect is Enabled; Same Priority Level on All PD Reminder. Priority disconnect examples are applicable only when there is inadequate power remaining to power an incoming device. When a PD is being connected to a port with the same priority level as all other in the slot, the physical port number is used to determine whether the incoming PD will be granted or denied power. Due to the support of different PoE standards and PoE hardware on each platform the internal port priority is differ- ent for each platform. The following tables should be used to determine PoE priority: OS6850 Physical Ports - 24 Port Models 1 (Highest) -> 24 (Lowest) OS6850E Physical Port - 24 Port Models 24 (Highest) -> 1 (Lowest) OS6850 Physical Ports - 48 Port Models 1 (Highest) -> 48 (Lowest) OS6850E Physical Port - 48 Port Models 48 (Highest) -> 1 (Lowest) PoE Physical Port PriorityPriority Disconnect is Enabled; Incoming PD Port has Highest Priority Level Reminder. Priority disconnect examples are applicable only when there is inadequate power remaining to power an incoming device. When a PD is being connected to a port with a higher priority level than all other in the slot, the incoming PD will automatically be granted power over the other devices, regardless of its physical port number. In order to avoid a power budget deficit, another port in the slot is disconnected. In determining which port to power off, the system software first selects the port with the lowest configured priority level. For exam- ple, if a critical priority device is being added to a slot in which five existing devices are attached to high priority and one device is attached to a low priority port, the low priority port is automatically discon- nected, regardless of its physical port number. If all existing devices are attached to with the same lower priority level, the system software disconnects the port with both the lowest priority level and the highest priority physical port number. For example, if a critical priority device is being added to a slot in which six existing devices are attached to high priority, the high priority port with the lowest physical port priority number is automatically disconnected.Priority Disconnect is Enabled; Incoming PD Port has Lowest Priority Level Reminder. Priority disconnect examples are applicable only when there is inadequate power remaining to power an incoming device. When a PD is being connected to a port with a lower priority level than all other in the slot, the incoming PD will be denied power, regardless of its physical port number. Devices connected to other higher-prior- ity will continue operating without interruption.page 5-10 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011

Managing OmniSwitch 6850/6850E Series Stacks OmniSwitch 6850/6850E Series Stack OverviewOmniSwitch 6850/6850E Series Stack Overview Users can configure up to eight switches, in any combination of chassis types, into a single virtual chassis known as a stack. With stacks, switching capacity can be easily expanded simply by adding additional switches to the stack. For example, a user can start with a stack composed of two switches and add up to six additional switches to that stack as network demands increase over time. Note. Switches should be added one at a time in a stack. Stacks also provide enhanced resiliency and redundancy features. If a switch in a stack goes down or is taken offline, the other elements in the stack will continue to operate without disruption. In addition, when a switch auto-synchronizes at boot-up, or if the user manually synchronize the switches (see “Synchroniz- ing Switches in a Stack” on page 6-39 for more information), operating software and configuration param- eters are backed up on all switches in the stack. As a result, the original operating software and configuration parameters can be easily recovered if corrupted or otherwise lost. Note on Terminology. The terms stack and virtual chassis are interchangeable referring to switches in a stacked configuration. The terms module, switch, slot, and element are used to refer to individual switches within a stacked configuration. The terms Chassis Management Module (CMM) and management module refer to those switches operating in a stack either in the primary or secondary management roles. Switches operating in an idle role are essentially acting as network interface modules and therefore may be referred to as Network Interfaces (NIs).Roles Within the Stack In order to operate as a virtual chassis, switches within a stack are assigned specific roles. These roles include primary and secondary management roles, idle status, and pass-through. For detailed descriptions of each of these roles, including their practical functions within the virtual chassis, refer to the sections below.Primary and Secondary Management Modules When switches operate in a stack, one switch in the stack always assumes the primary management role. This primary element is responsible for functions, such as software and configuration management, web- based management (i.e., WebView), SNMP management, switch diagnostics, and software rollback. One additional switch in the stack operates in a secondary management role. This switch serves as a backup, and is always ready to assume the primary management role in the stack if the switch with the primary role fails or is taken offline for any reason. Since the secondary module quickly and automatically assumes management responsibilities, switches operating in idle mode elsewhere in the stack continue to pass traffic without disruption. This redundancy provides effective safeguards for mission-critical network traffic and is one of the stack’s most important failover features. Diagrams showing the management module failover sequence for stacks of three or more switches and stacks of two switches are provided on pages 6-6 and 6-7, respectively.OmniSwitch 6850/6850E Series Hardware Users Guide June 2011 page 6-5

For management module redundancy to work effectively, the software on all switches operating in the stack must be synchronized at all times. Refer to “Synchronizing Switches in a Stack” on page 6-39 for more information. Primary 1 A stack of four switches is operating normally. The Secondary stack consists of a primary module, secondary module, and two elements operating in idle status. (The software Idle on all elements in the stack is synchronized.) Idle Offline !

Meanwhile, the adjacent switch—previously operating in idle status—now Secondary assumes the secondary management role. Idle Idle 4 If the switch that failed or was taken offline comes back Primary online, it will assume an idle role in the stack. In other words, it will act essentially as an NI module in the virtual Secondary chassis, passing traffic via its Ethernet.

  • 170. Roles Within the Stack Managing OmniSwitch 6850/6850E Series StacksPrimary Management Module Selection For a stack of switches to operate as a virtual chassis, there must be a mechanism for dynamically select- ing the switch within the stack that will assume the primary management role. OmniSwitch 6850/6850E Series switches use three different methods for selecting the primary switch. These methods are: • Chassis MAC address • Saved slot number • Chassis uptime Note. Information on secondary management module selection is provided on page 6-11. Information on dynamic assignment of idle module roles is provided on page 6-13. Using the Chassis MAC Address By default, the primary management role will be given to the switch with the lowest chassis MAC address. However, for this to occur, all switches in the stack must be booted within 15 seconds of each other. In addition, switches in the stack must have no preconfigured slot information. Because of these two condi- tions, the MAC address method for selecting the primary module usually occurs with new “out of the box” switches, or switches from which any preconfigured slot information has been cleared. For more information on using the lowest MAC address to determine the primary switch in a stack, refer to the diagram below: 1 A stack of four switches is booted. All switches are powered on within 15 seconds of each other. In addition, there is no preconfigured slot information on any of the switches. 00:d0:95:b2:3c:8e 2 When the stack is booted, system software detects the lowest 00:d0:95:b2:2a:ab MAC address. In this stacked configuration, the lowest 00:d0:95:b2:1c:ff MAC address is 00:d0:95:b2:1c:ff. 00:d0:95:b2:5b:8d 00:d0:95:b2:3c:8e 3 The system software immediately assigns the correspond- 00:d0:95:b2:2a:ab ing switch the primary management role. When the switch is assigned as primary, it is also dynamically assigned the Primary Module lowest slot number in the stack—i.e., slot 1. This slot 00:d0:95:b2:5b:8d number information is saved to the boot.slot.cfg file, located in the switch’s /flash file directory. Primary Management Module Selection Using the Lowest Chassis MAC Address Note. During the boot process, all other switches in the stack are also dynamically assigned unique slot numbers. As with the primary switch, these slot numbers are saved to the boot.slot.cfg file, located in the /flash file directory of each switch. For more information on dynamic slot number assignment, refer to “Slot Numbering” on page 6-22.page 6-8 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 171. Managing OmniSwitch 6850/6850E Series Stacks Roles Within the Stack Using Saved Slot Information The saved slot number is the slot number the switch will assume following a reboot. This information is stored in a switch’s boot.slot.cfg file; the switch reads its slot number assignment from this file at bootup and assumes the specified slot number within the stack. If switches in a stacked configuration have no preconfigured slot assignments, the slot number for each switch is dynamically assigned by the system software. Slot numbers can also be manually assigned by the user. For more information on manually assigning slot numbers, refer to “Manual Slot Number Assign- ment” on page 6-25. When a stack with preconfigured slot information is booted, it is not the lowest MAC address that deter- mines the primary management module. Instead, the slot information stored in each switch’s boot.slot.cfg is read by the system software and used in determining the primary. The switch with the lowest saved slot number becomes the primary management module. Note. Although, for ease-of-management purposes, it is recommended that slot numbers are assigned beginning with slot number 1, it is not a requirement. In other words, a stack of four switches can have slot assignments 3, 4, 5, and 6. However, it is important that each element in a stack is assigned a unique slot number. Do not assign duplicate slot numbers to elements in a stack. Otherwise, one or more switches will be forced into pass-through mode. For more information on pass-through mode, refer to page 6-14. For more information on using saved slot information to determine the primary switch in a stack, refer to the diagram below: Saved Slot 6 1 Four switches are stacked; all switches are connected via stack- Saved Slot 5 ing cables.

  • 172. Roles Within the Stack Managing OmniSwitch 6850/6850E Series Stacks Using Switch Uptime A user can override both the MAC address and saved slot methods for determining a stack’s primary management module. This is done by controlling the uptime of switches in the stack. If all elements of a stack are powered off, the user can force a particular switch to become primary by powering on that switch and waiting a minimum of 15 seconds before powering on any other switches. This can be useful if the user wants a switch placed in a specific location, e.g., the top-most switch in a stack, to become the primary. As with the lowest MAC address method, the primary management module is dynamically assigned slot number 1 when the stack is booted. For more information on using saved slot information to determine the primary switch in a stack, refer to the diagram below: Off 1 Four switches are stacked and connected via stacking cables. All Off switches are currently powered off. The user powers on a single switch in the stack. In this case, the bottom-most switch is powered on. Off Powered On Off 2 The user allows a minimum of 15 seconds to pass. Because no Off other switches have joined the stack, the switch that was powered Off on considers itself a stand-alone. The switch assumes a primary role by default—even if there is a high saved slot number in its Primary boot.slot.cfg file (e.g., 8). (Saved Slot 8) Powered On Powered On 3 The user now powers on the remaining switches in the stack in short Powered On succession. Primary (Saved Slot 8) Saved Slot 3 4 In this example, when the remaining switches come online, each has a lower saved slot value than the switch powered on at step 1. However, Saved Slot 1 the switch powered on at step 1—with its slot value of 8—retains its Saved Slot 2 primary management role. The joining switches are essentially ineligible for primary status because they are considered “late arrivals.” Primary (Saved Slot 8) For the primary switch to forfeit its role to the switch with the lowest assigned slot number (in this case, slot number 1), the stack must be rebooted by the user either by issuing the reload all command or by powering off and powering on all switches in close succession.

  • 173. Managing OmniSwitch 6850/6850E Series Stacks Roles Within the StackSecondary Management Module Selection In order to provide effective management module redundancy, all stacked configurations dynamically assign a backup, or secondary, management module during the boot process. Stacks use two different methods for selecting the secondary switch. These methods are: • Stacking connection to the primary switch • Saved slot number Using the Stacking Connection to the Primary Switch By default, the switch that is connected to the primary switch’s stacking port A is automatically assigned the secondary management role. This applies to stacks on which there is no preassigned slot information— i.e., there is no boot.slot.cfg file present in any switch. For more information on using the stacking connection to the primary switch to determine the secondary management module, refer to the diagram below: A B 1 Four switches are stacked and connected via stacking cables, as shown. All switches are currently powered off. None of the switches have preassigned slot numbers—i.e., there are no boot.slot.cfg files present. The user powers on all switches in the stack in close succession and the stack begins the boot process.

  • 174. Roles Within the Stack Managing OmniSwitch 6850/6850E Series Stacks Using Saved Slot Information If a stack with preassigned slot information for each switch is booted, the switch with the second lowest slot value is assigned the secondary management role. For example, if a stack of four switches is booted and the preassigned slot values for each switch are 1, 2, 3, and 4, the switch with the slot value of 2 is assigned the secondary role. Meanwhile, the switch with the slot value of 1 is assigned the primary management role (see page 6-9). For more information on using saved slot information to determine the secondary management module in a stack, refer to the diagram below: Saved Slot 1 1 Four switches are stacked; all switches are connected via stacking Saved Slot 3 cables. The user configures each switch to have a unique saved Saved Slot 4 slot number, as shown. When the saved slot number is configured, the information is automatically written to the boot.slot.cfg file Saved Slot 2 located in the /flash directory of each switch.

The switch with the Slot 4 second lowest assigned slot number becomes the secondary Secondary - Slot 2 management role, regardless of whether it is attached to stacking port A of the primary switch. In this case, the switch assigned slot 2 has the second-lowest slot number in the stack and becomes the secondary management module. Secondary Management Module Selection Using Saved Slot Information Reminder. Each element in a stack should always be assigned a unique slot number. Do not assign duplicate slot numbers to elements in a stack. Otherwise, one or more switches will be forced into pass-through mode.

  • 175. Managing OmniSwitch 6850/6850E Series Stacks Roles Within the StackIdle Module Role Switches that are not assigned either the primary or secondary role in a stack are, by default, assigned the role of idle modules. These idle modules operate similarly to Network Interface (NI) modules in a chassis- based switch. In the event of a management module failure within the stack, the idle module with the next lowest slot number in the stack will automatically assume the secondary management role. In other words, if the primary module in a stack goes down for any reason and the secondary takes over the primary manage- ment role, the switch must now assign a new secondary module. The idle element with the next lowest slot number assumes this new responsibility until the situation is corrected and all elements in the stack are reloaded. Note. Primary and secondary management modules also send and receive traffic on their Ethernet ports. The primary management module is like an NI module with the added task of overall stack management; the secondary management module is like an NI with the added responsibility of backing up the primary module in the event of a primary module failure. In other words, all modules in the virtual chassis can send and receive user data, regardless of their roles. For more information on dynamic assignment of idle modules in a stack, refer to the diagram below: 1 Four switches are stacked; all switches are connected via stacking cables. The stack is booted. 2 The primary and secondary management modules are dynamically assigned using any of the methods outlined on pages 6-8 through Primary 6-12. Secondary Idle 3 The system software automatically assigns the remaining elements Idle in the stack the idle module role. These modules act as Network Interface (NI) modules, sending and receiving 10/100/1000 Primary Ethernet traffic on their ports. Secondary In the event of a primary-to-secondary failover, the idle module with the next-lowest slot number in the stack will assume the secondary—or backup—management role.

  • 176. Roles Within the Stack Managing OmniSwitch 6850/6850E Series StacksPass-Through Mode The pass-through mode is a state in which a switch has attempted to join a stack but has been denied primary, secondary, and idle status. When a switch is in the pass-through mode, its Ethernet are brought down (i.e, they cannot pass traffic). Its stacking cable connections remain fully functional and can pass traffic through to other switches in the stack. In this way, the pass-through mode provides a mechanism to prevent the stack ring from being broken. However, note that when a switch comes up in pass-through mode, it should not be left unresolved. Pass-through mode is essentially an error state that should be corrected immediately by the user. Note. When a switch is in pass-through mode, its information will not display in hardware monitoring commands such as show chassis, show ni, show module, etc. Conditions that can trigger a switch to enter pass-through mode include: • Duplicate slot numbers or incorrect stacking modes have been assigned within the stack • The user has manually forced the switch into pass-through mode using the stack clear slot command Note. If a switch is forced into pass-through mode, the rest of the stack will not be disrupted. Any elements in the stack not operating in pass-through mode continue to operate normally. The most common reason for one or more switches to enter pass-through is duplicate slot number assign- ments within the stack. So, in order to avoid pass-through mode, it is useful to keep track of the current saved slot numbers on all elements in the stack. Slot number assignments are stored in the boot.slot.cfg file in the /flash directory of each switch. If the stack is booted and the same slot number is discovered on two or more switches, the switch with the lowest MAC address is allowed to come up and operate normally. Meanwhile, switches with the duplicate slot number and a higher MAC address come up in pass-through mode. To check the current slot number stored in each switch’s boot.slot.cfg file, use the show stack topology command. For example: -> show stack topology Link A Link A Link B Link B NI Role State Saved Link A Remote Remote Link B Remote Remote Slot State NI Port State NI Port ----+-----------+--------+------+-------+-------+-------+-------+-------+------- 1 PRIMARY RUNNING 1 UP 3 StackA UP 2 StackA 2 SECONDARY RUNNING 2 UP 1 StackB UP 3 StackB 3 IDLE RUNNING 2 UP 1 StackA UP 2 StackB In this example, note that both slots 2 and 3 have a saved slot value of 2. If this stack is rebooted, a dupli- cate slot error will occur and the switch with the lower MAC address will be given the secondary manage- ment role. The slot with the higher MAC address will be forced into the pass-through mode.page 6-14 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 177. Managing OmniSwitch 6850/6850E Series Stacks Roles Within the Stack To avoid a pass-through condition following a reboot, make sure that all saved slot values for the stack are unique. Use the stack set slot command. For example, change the saved slot value for the idle switch in slot 3 from 2 to 3: -> stack set slot 3 saved-slot 2 Use the show stack topology command to verify the change: -> show stack topology Link A Link A Link B Link B NI Role State Saved Link A Remote Remote Link B Remote Remote Slot State NI Port State NI Port ----+-----------+--------+------+-------+-------+-------+-------+-------+------- 1 PRIMARY RUNNING 1 UP 3 StackA UP 2 StackA 2 SECONDARY RUNNING 2 UP 1 StackB UP 3 StackB 3 IDLE RUNNING 3 UP 1 StackA UP 2 StackBRecovering from Pass-Through Mode (Duplicate Slot Numbers) The first step in recovering from pass-through is to determine which modules are currently operating in pass-through, as well as the reason for the pass-through state. To view this information, use the show stack topology command. For example: -> show stack topology Link A Link A Link B Link B NI Role State Saved Link A Remote Remote Link B Remote Remote Slot State NI Port State NI Port ----+-----------+--------+------+-------+-------+-------+-------+-------+------- 1 PRIMARY RUNNING 1 UP 1001 StackA UP 2 StackA 2 SECONDARY RUNNING 2 UP 1 StackB UP 1001 StackB 1001 PASS-THRU DUP-SLOT 2 UP 1 StackA UP 2 StackB Switches operating in pass-through mode are given distinct slot numbers. These slot numbers are not related to their position in the stack. Instead, they are assigned the prefix “100,” followed by the numeri- cal order in which they were forced into pass-through (1001–1008). Note. For pass-through elements 1001 through 1008, the slot indicator LED on the chassis front panel blinks 1 through 8, respectively. For example, if a module enters pass-through and has the slot number 1004, the LED for the module blinks the number 4. For more information on the slot indicator LED, refer to “Status LEDs” on page 2-53. In the example above, the switch with the NI (i.e., slot) number 1001 is operating in pass-through. Note that the role assignment is PASS-THRU; also, the state displays DUP-SLOT, or duplicate slot number. This can be further verified by looking down the saved slot column in the table. Note that slot 2, operating in the secondary management role, has a saved slot value of 2. Slot 1001, operating in pass-through, also has a saved slot value of 2.OmniSwitch 6850/6850E Series Hardware Users Guide June 2011 page 6-15
  • 178. Roles Within the Stack Managing OmniSwitch 6850/6850E Series Stacks To resolve this pass-through condition, simply assign slot 1001 a new saved slot value and reboot the module. This can be done in either of two ways: • Use the stack set slot command to assign the new value, then use the reload pass-through command to reboot the module: -> stack set slot 1001 saved-slot 3 -> reload pass-through 1001 • Use the stack set slot command to assign the new slot value and, using the optional reload syntax in the command line, reboot the module: -> stack set slot 1001 saved-slot 3 reload When the module comes up, it assumes the new, unique slot position—in this case, slot 3—and, because it now has the highest slot number in the stack, it assumes an idle role (leaving the primary and secondary roles to slots 1 and 2, respectively). There are now no duplicate numbers in the stack and all elements are operating normally: -> show stack topology Link A Link A Link B Link B NI Role State Saved Link A Remote Remote Link B Remote Remote Slot State NI Port State NI Port ----+-----------+--------+------+-------+-------+-------+-------+-------+------- 1 PRIMARY RUNNING 1 UP 3 StackA UP 2 StackA 2 SECONDARY RUNNING 2 UP 1 StackB UP 3 StackB 3 IDLE RUNNING 3 UP 1 StackA UP 2 StackBpage 6-16 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 179. Managing OmniSwitch 6850/6850E Series Stacks Roles Within the Stack In some pass-through conditions (for example, larger stacks where multiple switches are in pass-through mode), it might be desirable to correct any duplicate saved slot assignments and then reboot the entire stack. The recovery from pass-through can be accomplished with fewer steps than reassigning slot numbers and rebooting modules on a slot-by-slot basis. However, be sure that there is no mission-critical traffic being passed on the non-pass-though modules; traffic will be interrupted on these modules during the reboot.

Stacking Cables Stacking cables for can be connected in any pattern. In other words, the cable connected to stacking port A of one switch can be connected to either stacking port A or stacking port B of the adjacent switch. However, it is strongly recommended that the cabling pattern remains consistent across the stack. In addi- tion, for a stack to have effective redundancy, a redundant stacking cable must be installed between the upper-most and bottom-most switch at all times. This provides effective failover in the event of a stacking link or module failure within the stack. The diagram below shows two recommended stacking cable patterns.

Slot Numbering Managing OmniSwitch 6850/6850E Series StacksSlot Numbering For a stack of switches to operate as a virtual chassis, each module in the stack must be assigned a unique slot number. To view the current slot assignments for a stack, use the show ni or show module commands. The slot number is also displayed on the front panel of each switch by the LED located on the left side of the chassis (refer to “Status LEDs” on page 2-53 for more information). There are two ways stacking modules are assigned slot numbers: • Dynamic slot number assignment by the system software • Manual slot number assignment by the userpage 6-22 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 185. Managing OmniSwitch 6850/6850E Series Stacks Slot NumberingDynamic Slot Number Assignment Dynamic slot number assignment occurs when there are no boot.slot.cfg files present in the switches’ /flash directories. This is the case for new, “out of the box,” switches that have not been previously booted. When a brand new stack (or stack with no boot.slot.cfg files) is booted, the system software automati- cally detects the module with the lowest MAC address. This module is assigned the primary management role (see page 6-5) and, by default, is given the slot number 1. The module connected to the primary’s stacking port A is automatically assigned the secondary management role and given the slot number 2. As the other modules in the stack become operational, they are assigned idle roles and are automatically assigned unique slot numbers (3–8, depending on the number of switches in the stack). The slot number- ing for idle modules is determined by each module’s physical location in the stack. Refer to the diagrams below for more information on dynamic slot numbering. Note. As the slot numbers are dynamically assigned, boot.slot.cfg files are auto-generated in the /flash directory of each switch. When modules are subsequently booted, each switch reads its slot number assignment from this file and comes up accordingly. In this example, the fourth switch from the top is elected the primary management module for the stack. (It can be assumed that this switch has the lowest MAC address in the stack.) This switch is automatically assigned slot number 1.Slot 6 - IdleSlot 7 - Idle The switch immediately below is connected to the primary switch’s stacking port A and, as a result, isSlot 8 - Idle assigned the secondary management role and givenSlot 1 - Primary slot number 2.Slot 2 - Secondary The system software allows the switch immediately below slot 2 to have the next slot number preference.Slot 3 - Idle It is assigned an idle role and given the slot number 3.Slot 4 - Idle The switch immediately below slot 3 is given the slot number 4, and so on. When the bottom of the stack isSlot 5 - Idle reached, the slot numbering sequence resumes at the top of the stack, as shown. This helps ensure a more ordered and manageable stack topology.

  • 186. Slot Numbering Managing OmniSwitch 6850/6850E Series Stacks If the switch with the lowest MAC address happens to be the bottom-most module in the stack, slot numbering will not resume from the top of the stack. Instead, the system software will select the second- ary module using the standard method (i.e., the switch connected to the primary’s stacking port A), then continue to number the stack from the bottom up. This intuitive slot assignment provides the cleanest and most manageable stack topology. Refer to the diagram below for more information: In this example, the bottom switch is elected the primary management module for the stack. (It can be assumed that this switch has the low- est MAC address in the stack.) This switch is automatically assigned slot number 1.Slot 8 - IdleSlot 7 - Idle The switch immediately above is connected to the primary switch’s stacking port A and, as aSlot 6 - Idle result, is assigned the secondary managementSlot 5 - Idle role and given slot number 2.Slot 4 - Idle The system software then sequentially assigns slot numbers up the stack. In other words, theSlot 3 - Idle switch immediately above slot 2 is assignedSlot 2 - Secondary the slot number 3; the switch immediately above slot 3 is assigned the slot number 4, andSlot 1 - Primary so on. This default procedure ensures the most ordered and manageable stack topology out of the box. Dynamic Slot Numbering Example 2page 6-24 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 187. Managing OmniSwitch 6850/6850E Series Stacks Slot NumberingManual Slot Number Assignment To manually assign slot numbers to one or more modules in a stack, use the stack set slot command. This command writes slot information to the boot.slot.cfg file located in a switch’s /flash directory. It is this saved slot information that the switch will assume following a reboot. Manually assigning slot numbers can be useful in reordering existing slot numbers in order to create a sequential numbering scheme from the top of the stack to the bottom (or vice-versa). Refer to the follow- ing example: Slot 6 - Idle Slot 7 - Idle Slot 8 - Idle Slot 1 - Primary Slot 2 - Secondary Slot 3 - Idle Slot 4 - Idle Slot 5 - Idle This example, taken from page 6-23, shows a stack in which the primary and secondary switches are phys- ically positioned in the middle of the stack. Although the stack will operate normally with this primary and secondary module positioning, it may be preferable for management purposes to have the primary and secondary switches at either the top or the bottom of the stack. For this example, the primary and second- ary roles will be assigned to the top of the stack. This is accomplished by entering the following commands: -> stack set slot 6 saved-slot 1 -> stack set slot 7 saved-slot 2 -> stack set slot 8 saved-slot 3 -> stack set slot 1 saved-slot 4 -> stack set slot 2 saved-slot 5 -> stack set slot 3 saved-slot 6 -> stack set slot 4 saved-slot 7 -> stack set slot 5 saved-slot 8 -> reload all Because slot 6 is the top-most switch in the stack, it is reassigned the slot 1 (i.e., primary) position; because slot 7 is located immediately below slot 6, it is reassigned the slot 2 (i.e., secondary) position, etc. Note that the modules were not reloaded one-by-one, even though the stack set slot command provides optional syntax for doing so. Instead, new slot number information is first saved to each boot.slot.cfg file across the stack. The reboot is saved for last in order to avoid duplicate slot numbers within the stack, which would cause unwanted pass-though mode conditions (see page 6-14).OmniSwitch 6850/6850E Series Hardware Users Guide June 2011 page 6-25
  • 188. Slot Numbering Managing OmniSwitch 6850/6850E Series Stacks When the stack comes up following the reboot, the manually-configured slot numbers display as follows: Slot 1 - Primary Slot 2 - Secondary Slot 3 - Idle Slot 4 - Idle Slot 5 - Idle Slot 6 - Idle Slot 7 - Idle Slot 8 - Idle The stack set slot command can also be used to manually correct duplicate saved slot assignments within the stack topology. Refer to pages 6-14 through 6-16 for detailed information.Reverting to the Dynamic Slot Numbering Model To clear the boot.slot.cfg files from the stack’s /flash directories, use the stack clear slot command on all modules and then reboot the stack. For example: -> stack clear slot 1 -> stack clear slot 2 -> stack clear slot 3 -> stack clear slot 4 -> stack clear slot 5 -> stack clear slot 6 -> stack clear slot 7 -> stack clear slot 8 -> reload all The commands shown above clear the saved slot information from all modules in an eight-module stacked configuration and then reboot the stack. Because the system software no longer has preassigned slot infor- mation to read during the boot process, the stack uses the dynamic slot number assignment method described on page 6-23.page 6-26 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 189. Managing OmniSwitch 6850/6850E Series Stacks Hot-Swapping Modules In a StackHot-Swapping Modules In a Stack Modules within a virtual chassis are hot-swappable. NI modules are essentially those modules operating in the stack in idle mode. These modules can be removed from, or added to, an existing stack without disrupting other modules in the stack.Removing Switches from an Existing Stack When removing switches from an existing stack, observe the following important guidelines: • Do not attempt to hot-swap modules operating in primary or secondary management roles • Be sure the stacking cables and stacking cable redundancy are not disrupted Hot-swapping is intended for switches in idle and, if applicable, pass-through status only. Removing primary or secondary management modules from a stack will trigger a failover sequence, i.e., one or more additional modules within the stack must reload in order to reassign the management roles. Whenever possible, avoid removing a switch that is operating as a primary or secondary management module. Also, removing a switch from a stacked configuration can disrupt stack cabling at the rear of the stack. When removing a module, be sure that stacking link integrity, including important stacking cable redun- dancy, is maintained between all remaining modules. For more information on stacking cable connec- tions, refer to page 6-18.Inserting Switches Into an Existing Stack When inserting switches into an existing stack, observe the following important guidelines: • Avoid duplicate saved slot numbers • Never attempt to operate more than eight switches in a single stack • Make sure all switches are running the same software version. To avoid duplicate slot numbers, simply make sure that any modules being added to an existing stack have been cleared of preassigned slot information. In other words, verify that there is no boot.slot.cfg file present in the /flash directory of any switch being added. When the switch is connected to the existing stack and booted, the system software automatically assigns it a unique slot number. No duplicate slot errors occur. Note. If it is preferable to add a switch with an existing boot.slot.cfg file to a stack, be sure that the saved slot number of the incoming switch is not already assigned to a switch operating in the stack.OmniSwitch 6850/6850E Series Hardware Users Guide June 2011 page 6-27

Hot-Swapping Modules In a Stack Managing OmniSwitch 6850/6850E Series StacksMerging Stacks Merging stacks involves connecting two or more operational stacks and attempting to reboot them as a single virtual chassis. In most cases, errors will result. To merge stacks without causing errors, select one stack that is to remain up and running and then add modules from the other stack(s) by following the steps below: 1 Make sure all switches are running the same software version. 2 Clear the saved slot information from all incoming modules. This will ensure that they are each assigned unique slot numbers when they join the stack. 3 After clearing the saved slot information, power off all incoming modules. 4 Connect the stacking cables for all incoming modules to the existing, operational stack as required. Be sure to provide stacking cable redundancy. For information on stack cabling, refer to page 6-18. 5 Power on all incoming modules. Note. No more than eight switches can operate in a single stacked configuration at any time.page 6-28 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011

Users can reload stacked modules operating in any role— i.e., primary, secondary, idle, and pass-through. Refer to the sections below for more information.Reloading the Primary Management Module If the switch with the primary management role is reloaded, the switch with the secondary role automati- cally takes over primary management functions. In other words, the switch with the secondary role assumes the primary role as soon as the reload is initiated. Meanwhile, the idle switch with the next lowest slot number automatically assumes the secondary role. When the reloaded switch (the former primary module) comes back up, it assumes an idle role within the stack. To reload the primary management module, use the reload command. The optional syntax primary can be used in the command line, but is not required. For example: -> reload primary Note. A primary management module reload can also be scheduled for a later time or date.

  • 195. Managing OmniSwitch 6850/6850E Series Stacks Reloading SwitchesReloading Switches with Idle Roles Similar to reloading Network Interface (NI) modules on chassis-based switches modules operating in idle status within a stack can be reloaded via the CLI. Note. Any traffic being passed on the module’s Ethernet will be interrupted during the reboot. Other modules within the stack will continue to operate without interruption. To reset a single module operating in idle mode, use the reload ni command. Be sure to include the slot number of the idle switch in the command line. For example: -> reload ni 3 Only one idle switch can be reloaded at a time. In order to reload multiple idle switches at once, the entire stack must be reloaded using the reload all command. After reloading a switch operating in an idle role, the switch resumes idle status when it comes back up, despite its saved slot number. In other words, if an idle switch with a saved slot number of 1 is reloaded, it resumes its previous idle role. Although it has the lowest possible saved slot number, it does not take over the primary management role. In order for this switch to take over the primary role, all switches in the stack must be reloaded. Note. For more information on reloading all the switches in a stack, refer to page 6-34. For more informa- tion on idle status, refer to page 6-13.Reloading Switches in Pass-Through Mode Pass-through mode is a state in which a switch has attempted to join a stack but has been denied primary, secondary, and idle status. Because this is essentially an error state, the pass-through condition must be resolved and any modules operating in pass-through mode must be reloaded. To reload a module operating in pass-through mode, use the reload pass-through command. Be sure to include the slot number of the pass-through switch in the command line. For example: -> reload pass-through 1001 Note. Before issuing the reload pass-through command, be sure to resolve any conditions causing the switch to operate in pass-through mode. Otherwise, the switch is likely to come up again in pass-through mode. For detailed information, including steps used to recover from pass-through, refer to page 6-14.OmniSwitch 6850/6850E Series Hardware Users Guide June 2011 page 6-33
  • 196. Reloading Switches Managing OmniSwitch 6850/6850E Series StacksReloading All Switches in a Stack Reloading all switches in the stack is essentially a full reboot of the virtual chassis. This can be useful in restoring a stack’s previously configured topology—i.e., the stack’s saved slot numbers and management roles. Note, however, that all data flow on the stack is interrupted whenever a full reboot is issued. To reset all switches in a stack use the reload all command. For example: -> reload all Important. Before issuing the reload all command, be sure to read the sections below. Understanding topics such as software synchronization and the effects of saved slot information can help users avoid unexpected results following a full stack reboot.Software Synchronization During a Full Reload If the checksum value on the stack’s non-primary switches differs in any way from the checksum value on the primary switch, the primary switch automatically distributes its system and configuration software to all other switches in the stack whenever a full reload is executed. During this automatic software synchronization, system and configuration software on the secondary and idle switches is overwritten. Because the primary switch’s “last known good” software is propagated to all switches, the synchronization process helps ensure effective redundancy across the stack.Effects of Saved Slot Number Information on the Reload Process Depending on the status of saved slot information across the stack, there are different slot numbering and management role scenarios that can occur following a full reboot. For this reason, checking the current stack topology before issuing a full reboot is strongly recommended. To check the current stack topology, use the show stack topology command. Refer to the OmniSwitch CLI Reference Guide for detailed command information. Possible saved slot number conditions include: • All switches have unique saved slot information • No switches in the stack have saved slot information • Some switches have saved slot information, others do not • Two or more switches have duplicate slot information All Switches Have Unique Saved Slot Information If a full reload is issued and all switches have unique slot numbers saved to their boot.slot.cfg files, the slot numbers will be assigned according to the saved slot information. The primary management role will be given to the switch with the lowest saved slot number. The secondary management role will be given to the switch with the second-lowest saved slot number. All other switches will be assigned to idle roles. An illustrated example of this method for assigning slot numbers and management roles is provided on pages 6-25 and 6-26.page 6-34 OmniSwitch 6850/6850E Series Hardware Users Guide June 2011
  • 197. Managing OmniSwitch 6850/6850E Series Stacks Reloading Switches No Switches In the Stack Have Saved Slot Information If a full reload is issued and no switches in the stack have unique slot numbers, slot numbers will be assigned beginning with the switch with the lowest MAC address. (This can occur if the boot.slot.cfg file has been deleted from each switch’s /flash directory—e.g., by issuing the stack clear slot command for all modules in the stack.) The switch with the lowest MAC address is assigned slot number 1 and given the primary management role. The switch connected to stacking port A of the primary switch is automatically assigned slot number 2 and given the secondary management role. Stack cabling is then used to determine the dynamic slot numbering of the remaining modules in the stack. The switch immediately adjacent to slot 2 is assigned slot number 3 and given an idle role, etc. An illustrated example of this method for assigning slot numbers and management roles is provided on pages 6-23 and 6-24. Some Switches Have Saved Slot Information, Others Do Not If only some switches in the stack have boot.slot.cfg files in their /flash directories, the system software will first read the contents of these files and then dynamically assigns unique slot numbers to any switches that do not have saved slot information. The primary management role will be given to the switch with the lowest saved slot number. The secondary management role will be given to the switch with the second- lowest saved slot number. All other switches will be assigned to idle roles. When unique slot numbers are dynamically assigned by the system software, a boot.slot.cfg file is auto- matically generated with the new slot information. Because all switches now have unique saved slot infor- mation, any subsequent reload all commands issued will cause the stack to come up as described in the section, “All Switches Have Unique Saved Slot Information” on page 6-34. Two or More Switches Have Duplicate Slot Information If a full stack reboot is issued and the same slot number is found in the boot.slot.cfg file of two or more switches, the switch with the lowest MAC address is allowed to come up and operate normally. Mean- while, any other switches with the duplicate slot number come up in pass-through mode. The pass-through mode is essentially an error state in which a switch has been denied primary, secondary, and idle roles within the stack. When a switch is in pass-through mode, its Ethernet are brought down and cannot pass traffic. It is for this reason that users should always check the current saved slot number for each switch before issuing the reload all command. To check the current saved slot information across the stack, use the show stack topology command. For detailed information on pass-through mode, refer to “Pass-Through Mode” on page 6-14.OmniSwitch 6850/6850E Series Hardware Users Guide June 2011 page 6-35
  • 198. Reloading Switches Managing OmniSwitch 6850/6850E Series StacksAvoiding Split Stacks The term “splitting” a stack refers to the creation of isolated modules within the virtual chassis. A split stack can result from the following conditions: • Two or more non-adjacent switches are reloaded simultaneously • The stack is reloaded without a redundant stacking cable connection The sections below offer simple guidelines for avoiding splitting the stack during the reload process. Do Not Reload Non-Adjacent Switches Simultaneously If non-adjacent switches in the stack—for example, the top switch in the stack and the third-from-top switch in the stack—are reloaded simultaneously, a problem will occur. The switch between the two non- adjacent switches will become isolated and the virtual chassis will be effectively split. To avoid splitting the stack, do not reload the two non-adjacent switches simultaneously. Instead, simply reload the top switch first, then reload the third-from-top switch, or vice-versa. Be Sure a Redundant Stacking Cable is Installed at All Times Another important guideline for avoiding split stacks involves the redundant stacking cable. In order to avoid isolated modules within the virtual chassis, simply make sure that a redundant stacking cable connection exists between the top-most and bottom-most switches at all times.

  • 199. Managing OmniSwitch 6850/6850E Series Stacks Changing the Secondary Module to PrimaryChanging the Secondary Module to Primary Stacks allow users to manually force the secondary switch to assume the primary management role. This is referred to as “takeover.” The behavior of a takeover is similar to that of reloading the primary manage- ment module (see page 6-29). Whenever a takeover is initiated, the switch with the secondary role automatically takes over primary management functions. The primary switch is automatically reloaded and any traffic being passed on the primary switch’s Ethernet is interrupted. Meanwhile, the idle switch with the next-lowest slot number automatically assumes the secondary role. When the former primary module comes back up, it assumes an idle role within the stack. To initiate a takeover sequence, use the takeover command. For example: -> takeover Note. Before using the takeover command, verify that the switches in the stack are synchronized. Otherwise, data flow and switch management functions may be interrupted due to incorrect or outdated software when a switch takes over the primary management role.

  • 201. Managing OmniSwitch 6850/6850E Series Stacks Synchronizing Switches in a StackSynchronizing Switches in a Stack Management module synchronization refers to the process of copying all files in the /flash/working and /flash/certified directories of the primary management module to the /flash/working and /flash/certified directories of all the other switches in the stack. The system and configuration software on the non- primary switches—i.e., the secondary management module and any modules operating in idle—is over- written. The synchronization process ensures that the contents of these directories match exactly for all switches across the stack. This can be especially useful after new software has been loaded to the primary manage- ment module. Further, synchronization prevents any switch from assuming a management role within the stack with incorrect or outdated software or configuration files. Because the primary switch’s “last known good” software is propagated to all switches, the synchronization process helps ensure effective redun- dancy across the stack. In order to maintain effective management module redundancy, switches in the stack must be synchro- nized at all times. To determine whether a stack is in need of synchronization, use the show running- directory command. For example: -> show running-configuration CONFIGURATION STATUS Running CMM : PRIMARY, CMM Mode : DUAL CMMs, Current CMM Slot : 1, Running configuration : WORKING, Certify/Restore Status : CERTIFY NEEDED SYNCHRONIZATION STATUS Flash Between CMMs : NOT SYNCHRONIZED, Running Configuration : NOT AVAILABLE, Stacks Reload on Takeover: PRIMARY ONLY This example shows a switch on which the /flash directories between the management modules are not synchronized. To manually synchronize all switches in the stack, enter the following command: -> copy working certified flash-syncro When the synchronization process is initiated, modules within the stack continue to operate without inter- ruption and data flow across the stack is unaffected.Automatic Synchronization During a Full Reload If the checksum value on the stack’s non-primary switches differs in any way from the checksum value on the primary switch, the primary switch automatically distributes its system and configuration software to all other switches in the stack whenever a full reload is executed. For more information on initiating a full reload, see “Reloading All Switches in a Stack” on page 6-34. Note.
